Solar glass is one of the most important materials behind every solar panel. It protects the solar cells from dust, rain, wind and impact, while allowing maximum sunlight to pass through. A good solar glass must be strong, clear, low-iron, properly tempered and suitable for long outdoor life.
India’s solar module manufacturing industry is growing very fast, but solar glass manufacturing is still a limited sector. Unlike TMT bars, cement or steel, India does not have ten large pure solar PV glass manufacturers. So this 2026 list is practical: the top names include dedicated solar glass makers first, followed by major flat glass and processed glass companies that are important to India’s solar glass supply chain.
For this 2026 list, the ranking is based on solar glass product range, manufacturing capacity, PV glass relevance, glass processing strength, market presence, expansion plans and importance in India’s renewable-energy manufacturing ecosystem.
Now let’s check out the top 10 solar glass manufacturers in India in 2026.
1. Borosil Renewables Limited
Borosil Renewables ranks first because it is the clearest pure-play solar glass name in India. The company calls itself a premier solar glass manufacturer and offers products such as low-iron textured solar glass, 2 mm fully tempered solar glass, anti-reflective coated glass, anti-soiling coated glass, anti-glare solar glass and grid-printed back glass for bifacial solar modules. Its website mentions around 1,350 TPD manufacturing capacity, equivalent to nearly 8.5 GW of solar glass capacity.
The company’s Bharuch facility in Gujarat is the heart of its Indian operations. Borosil has also acquired Interfloat in Europe, giving it international strength. In India’s solar glass sector, Borosil remains the most trusted and visible name.
2. Gold Plus Float Glass Private Limited
Gold Plus has become an important name in India’s solar glass industry. Its solar glass catalogue mentions 300 tonnes per day of solar glass capacity, equivalent to solar glass for around 2 GW of solar modules. The company also offers solar glass in 2 mm, 2.5 mm, 2.8 mm, 3.2 mm and 4 mm thicknesses.
Gold Plus is already a major float glass manufacturer with plants in states such as Uttarakhand, Himachal Pradesh and Karnataka. Its move into photovoltaic glass makes it one of the most serious challengers in India’s solar glass market. With growing demand from domestic solar module makers, Gold Plus has strong future potential.
3. Avaada Electro / Avaada Group
Avaada is better known for solar modules, cells and renewable energy projects, but it deserves a place in this list because of its solar glass expansion plan. A 2026 report said Avaada plans to establish a separate solar glass unit in Nagpur using locally sourced sand, as part of its larger integrated solar manufacturing chain.
The company already has a large solar module manufacturing setup and is moving toward deeper backward integration. If its solar glass plan is executed well, Avaada can become one of the most important Indian names in the solar glass supply chain.
4. Saint-Gobain Glass India
Saint-Gobain is one of the biggest glass companies operating in India. Its Indian glass business offers clear glass, toughened glass, energy-efficient glass, solar control glass, fire-safety glass and other advanced glass solutions.
Saint-Gobain is not counted here as a pure Indian solar PV glass producer like Borosil. However, its manufacturing experience, coating technology, processing network and large Indian presence make it an important company in the broader solar glass and high-performance flat glass ecosystem.
5. Asahi India Glass Limited – AIS
Asahi India Glass, also known as AIS, is a major Indian glass company serving automotive, building, construction, consumer and industrial glass markets. Its official website describes it as India’s leading integrated glass and window solutions company with product solutions across automotive, building and consumer glass.
AIS is not mainly known as a solar PV glass producer, but it is important because solar glass requires high-quality flat glass processing, tempering and coating strength. With India’s solar manufacturing demand rising, companies like AIS can play a stronger future role in the solar glass ecosystem.
6. Gujarat Guardian Limited
Gujarat Guardian is linked with Guardian Glass, a global glass group known for flat glass, coated glass, insulated glass, laminated glass and tempered glass products. Guardian Industries is known globally for float glass and fabricated glass products for commercial, residential and automotive applications.
Gujarat Guardian is not usually seen as a pure solar panel glass brand in India, but its flat glass base keeps it relevant. Solar glass demand needs low-iron and processed flat glass capacity, and companies from this segment can become important suppliers or technology partners as the market expands.
7. Şişecam / Trakya Glass India
Şişecam is a major international glass manufacturer with a wide product range across flat glass, glassware, packaging glass and industrial materials. It is counted among the large global flat glass manufacturers, with operations across several countries.
In the Indian context, Şişecam/Trakya’s importance comes from its flat glass and processed glass background. It is not a leading Indian-origin solar PV glass company, but it remains relevant in the wider glass manufacturing ecosystem that can support solar, construction and industrial glass demand.
8. Sejal Glass Limited
Sejal Glass is one of India’s recognized glass processors. Its product range includes solid glass, Kool Glass, Tone Glass, Fort Glass, Armor Glass, Decor Glass and fire-safety glass products. The company also describes itself as one of the preferred processors in India.
Sejal Glass is not a large primary solar PV glass manufacturer. Still, it is included because solar glass manufacturing also depends on processing skills such as tempering, coating, lamination and edge finishing. Its processed-glass experience gives it a place in the broader solar glass ecosystem.
9. Hindusthan National Glass & Industries Limited
Hindusthan National Glass & Industries is mainly known for food, beverage, pharmaceutical, liquor, cosmetics and household glass containers. Its official site lists product categories such as food and beverages, pharmaceutical and wellness, beer and liquor, and household and cosmetics.
HNGIL is not a solar PV glass specialist. It is included lower in the list only because India has limited pure solar glass producers, and HNGIL remains part of the country’s wider glass manufacturing base. For actual solar PV glass, Borosil and Gold Plus are far more directly relevant.
10. PGP Glass
PGP Glass is a large Indian glass packaging company with strong manufacturing capability. Its official site mentions over 40 years of experience, five furnaces, more than 30 production lines and around 1,400 tonnes produced per day.
PGP Glass does not primarily manufacture solar PV glass. Its main focus is glass packaging for cosmetics, perfumery, specialty food, spirits and pharmaceuticals. Still, it shows the scale and strength of India’s glass manufacturing industry, which is important as the country tries to localize more solar supply-chain materials.
Final Words
India’s real solar glass manufacturing industry in 2026 is led mainly by Borosil Renewables and Gold Plus, while Avaada is emerging as a serious future player through its planned solar glass unit. Saint-Gobain, AIS, Gujarat Guardian, Şişecam, Sejal Glass, HNGIL and PGP Glass are more connected with the wider flat glass and processed glass ecosystem. As India expands solar module, cell and wafer manufacturing, the demand for local solar glass will rise strongly, making this sector one of the most important parts of the clean-energy supply chain.
